TRIzol reagent is a mono-phasic solution of phenol and guanidine isothiocyanate. I am trying to extract total RNA from a plant. My lab doesn't do biology/biochemistry at all, so this is a bit beyond us. I borrowed reagents to extract RNA and do RT-PCR last time I did this experiment, but now I'm doing it on my own and I'm wondering if it's possible to do RNA extraction without the TRIzol...Four RNA isolation methods were compared in this study. Three of these methods are based on commercial kits: TRIzol reagent (Invitrogen, Carlsbad, CA), the SV Total RNA isolation system (Promega, Madison, WI), and the RNeasy Mini Kit (Qiagen, Hilden, Germany). The remaining RNA isolation method is a complex CTAB-based method (Baiges and Mas 2003). Reagents for the CTAB-based method were purchased from the Merck group (Merck, South Africa). No proof for the rna being of viral origin. Now the question is: What is required first for virus isolation/proof? We need to know where And because the PCR tests are calibrated for gene sequences (in this case RNA sequences because SARS-CoV-2 is believed to be a RNA virus), we...
As with DNA isolation, scientists commonly rely on RNA isolation kits to make their life easier. Recently, we published a blog on DNA purification without a kit that outlined several reasons why doing something without a kit has advantages: less plastic waste, less expense, and less of being left with a bunch of random solutions when all the spin columns run out.
